BACKGROUND Initiated and regulated by mast cells, allergic responses are balanced through an intricate network of positive and negative signals. We have recently shown that the inhibitory receptor CD300a is expressed on human mast cells and modulates a large array of their functions. OBJECTIVE We sought to evaluate CD300a as a negative regulator of allergic inflammation in vivo by means of a ...
There is an urgent need of adjuvants for cutaneous vaccination. Here, we report that micro-sterile inflammation induced at inoculation sites can augment immune responses to influenza vaccines in animal models. The inoculation site is briefly illuminated with a handheld, non-ablative fractional laser before the vaccine is intradermally administered, which creates an array of self-healing microth...
Ticks are unique among hematophagous arthropods by continuous attachment to host skin and blood feeding for days; complexity and diversity of biologically active molecules differentially expressed in saliva of tick species; their ability to modulate the host defenses of pain and itch, hemostasis, inflammation, innate and adaptive immunity, and wound healing; and, the diverse array of infectious...
Unfettered inflammation is thought to play critical role in the development of different clinical forms of tegumentary leishmaniasis. Eicosanoids are potent mediators of inflammation and tightly associated with modulation of immune responses. In this cross-sectional exploratory study, we addressed whether targets from the eicosanoid biosynthetic pathway, assessed by multiplexed expression assay...
The chemokine thymus and activation-regulated chemokine (TARC; CCL17) is displayed by cutaneous (but not intestinal) venules, and is thought to trigger vascular arrest of circulating skin homing memory T cells, which uniformly express the TARC receptor CC chemokine receptor (CCR)4. Cutaneous T cell-attracting chemokine (CTACK; CCL27), expressed by skin keratinocytes, also attracts cutaneous mem...
BACKGROUND Chronic inflammation is a characteristic feature of diabetic cutaneous wounds. We sought to delineate novel mechanisms involved in the impairment of resolution of inflammation in diabetic cutaneous wounds. At the wound-site, efficient dead cell clearance (efferocytosis) is a pre-requisite for the timely resolution of inflammation and successful healing. METHODOLOGY/PRINCIPAL FINDIN...
Distinguishing cutaneous infection from sterile inflammation is a diagnostic challenge and currently relies upon subjective interpretation of clinical parameters, microbiological data, and nonspecific imaging. Assessing characteristic variations in leukocytic infiltration may provide more specific information. In this study, we demonstrate that homing of systemically administered monocytes tagg...
Endothelial cells form a multifunctional cell lining that covers all of the inner surface of blood vessels and regulates several important physiological and pathological reactions. These include inflammation/immune reaction, blood vessel tonus, hemostasis/thrombosis, angiogenesis and so on. Behçet’s Disease (BD) is a chronic, relapsing, multisystemic disorder characterized by urogenital ulcers ...
Bilateral neuroretinitis and anterior uveitis following ipilimumab treatment for metastatic melanoma
BACKGROUND This report presents a novel case of bilateral neuroretinitis and anterior uveitis in a patient receiving ipilimumab treatment for metastatic cutaneous melanoma and summarizes the literature regarding treatment options for patients with ipilimumab-related ocular immune-related adverse events. FINDINGS The medical chart was reviewed, a literature search was performed, and the result...
In this review article we discuss current knowledge about iron in the skin and the cutaneous wound healing process. Iron plays a key role in both oxidative stress and photo-induced skin damage. The main causes of oxidative stress in the skin include reactive oxygen species (ROS) generated in the skin by ultraviolet (UVA) 320-400 nm portion of the UVA spectrum and biologically available iron. We...
